Cruchley Ice Piedmont
Cruchley Ice Piedmont () is an ice piedmont between the east margins of Powell Island and its north–south range of hills, extending northward from the John Peaks, in the South Orkney Islands The South Orkney Islands are a group of islands in the Southern Ocean, about north-east of the tip of the Antarctic PeninsulaUK Antarctic Place-Names Committee in 1987 that historically derives from James Weddell's map of 1825 on which Powell Island is charted as two islands, the southern one being "Cruchley's Island."

Powell Island
Powell Island is a narrow island long and wide, lying between Coronation and Laurie Islands in the central part of the South Orkney Islands of Antarctica. Its southern end lies 7 km east of the south-western extremity of Coronation Island, between Lewthwaite Strait and Washington Strait. History The island was discovered in the course of the joint cruise by Captains George Powell and Nathaniel Palmer in December 1821. It was correctly charted, though unnamed, on Powell's map published in 1822; it was subsequently named for Powell on an Admiralty chart of 1839. Birds An area including part of southern Powell Island (south of John Peaks on Coronation Island), along with neighbouring Christoffersen, Fredriksen, Michelsen and Grey Islands, with some other (unnamed) islands lying offshore, has been identified as a 2688 ha Important Bird Area (IBA) by BirdLife International as it supports several significant seabird breeding colonies. The boundary of the IBA is defin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Peaks
The John Peaks () are prominent snow-covered peaks, high, at the southern end of Coronation Island, north of Powell Island and east of Signy Island in the South Orkney Islands. They were probably first sighted by Captain George Powell and Captain Nathaniel Palmer, who discovered these islands in December 1821. The peaks were charted in 1933 by Discovery Investigations personnel on the ''Discovery II'' who named them for D.D. John, a member of the zoological staff of the Discovery Committee The Discovery Committee was a popular name for the Interdepartmental Committee for the Dependencies of the Falkland Islands established by the British Government to carry out scientific investigations (which became known as ‘Discovery Investigati ....

UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by Scientific Committee on Antarctic Research, SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Weddell
James Weddell (24 August 1787 – 9 September 1834) was a British sailor, navigator and seal hunter who in February 1823 sailed to latitude of 74° 15′ S—a record 7.69 degrees or 532 statute miles south of the Antarctic Circle—and into a region of the Southern Ocean that later became known as the Weddell Sea. Early life He was born in Ostend on the Belgian coast, the son of a Scottish sea captain (captains were permitted their wives at sea). He was apprenticed as a seaman (this normally started at age eight) and so received little education, but clearly could at least read and write. He originally worked on merchant ships on the north-east Scottish coast. He entered the merchant service very early in his life and was apparently bound to the master of a Newcastle upon Tyne, Newcastle Collier (ship type), collier (a coal transport vessel) for some years. About 1805 he shipped on board a merchantman trading to the West Indies, making several voyages t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Piedmonts Of Antarctica
Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on its his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
